摘要： Embodiments include a communication system including host computer, base station, and UE, and methods therein. The host computer provides user data and initiates a transmission carrying the user data to the UE via a cellular network comprising the base station. The UE receives, from the base station, an indication of an active bandwidth part (BWP), which is of size NBWP,1size in number of frequency-domain resource blocks (RBs). The UE receives an indication of one or more frequency-domain RBs assigned within the active BWP for carrying the user data. The indication is encoded based on a size NBWP,2size (

摘要： Embodiments herein disclose e.g. a method performed by a wireless device (10) for handling communication for the wireless device in a second wireless communication network. The second wireless communication network coexists with a first wireless communication network on a same bandwidth in frequency, wherein the first wireless communication network applies a first shift in frequency in uplink transmissions. The wireless device receives from a radio network node (12, 13), an indication indicating application of a second shift in frequency to uplink transmissions in case the second wireless communication network uses Frequency Division Duplex (FDD). The wireless device further applies the second shift in frequency to uplink transmissions, wherein the second shift defines a shift in frequency to a subcarrier relative to a subcarrier grid of the second wireless communication network or a shift in frequency to the subcarrier grid of the second wireless communication network.

摘要： Methods and apparatuses provide for the determination and use of a same minimum processing time for a UE (10) with respect to scheduling the UE (10) on a scheduled carrier. In one embodiment a method includes determining (1102) a same minimum processing time for a User Equipment (UE) (10) to be at least as large as the largest one of a first minimum processing time that applies with respect to use of a first scheduling carrier to schedule the UE (10) on a scheduled carrier and a second minimum processing time N that applies with respect to use of a second scheduling carrier to schedule the UE (10) on the scheduled carrier; and scheduling (1104) the UE (10) on the scheduled carrier according to the same minimum processing time, irrespective of whether the first or second scheduling carrier is used for the scheduling. Determining and using a same minimum processing time that is applied commonly regardless of which scheduling carrier is used for scheduling the UE (10) on the scheduled carrier obviates the need to base scheduling decisions in the network and operating decisions at the UE (10) on legacy per-carrier minimum processing times. Use of the same minimum processing time commonly across the two scheduling carriers also avoids processing stalls or other problems that can arise at the UE (10) in cross-carrier scheduling scenarios involving multiple scheduling carriers of differing numerologies and the use of legacy per-carrier minimum processing times.

摘要： There is disclosed a method of operating a network node, the network node operating according to a first radio access technology, RAT. The method includes transmitting signaling having communication signaling and Demodulation Reference Signaling, DMRS, in a transmission resource pattern. The DMRS is arranged in the transmission resource pattern according to a DMRS pattern, in which the DMRS pattern is selected from a set of DMRS patterns based on a coexistence indication indicating the presence of cell-specific reference signals, CRS, associated to a second RAT.
